Please tell us if this helped!

Flash for IE (ActiveX version) and Flash for FF are separate downloads. So make sure you download the version for FF and install it.

markat22,

The browser you posted here with has Shockwave Flash 13.0 r0 installed for Firefox.

See if anything here helps you:

You can try to run the Flash installer as Administrator (right-click: Run as Administrator).

Also make sure to only install updates by visiting the official web page of its makes and never via a pop-up that you might get when visiting a website as such a pop-up is likely a scam to get you infected.

Thanks Cor-el for this. I have tried running as administrator as you suggest, but no better result. I think my problem might ba a microsoft issue rather than Mozilla or Adobe.

Thanks the-edmeister, but that is my problem, the Shockwave plugin is not on the list of plugins for Firefox - if it was I don't think I would have a problem.
